Quick answer: The XingXiu DSP400L-0304-BA power supply converts AC mains input into two regulated DC output channels: 4.2VDC and 3.2VDC. It provides 321W normal output power for compatible LED display systems and industrial electronic equipment.
XingXiu DSP400L-0304-BA power supply overview
The BA version uses an LLC conversion topology with precise control and input-to-output isolation. Its 90-264VAC input range supports common 100-240VAC installations, while the dual low-voltage outputs serve equipment designed specifically for 4.2V and 3.2V rails.
Model suffixes matter. The DSP400L-0304-BA is not interchangeable with a similarly named power supply unless the output voltages, connector layout, pinout, power demand, mounting dimensions, and cooling requirements all match.

Frequently asked questions
What are the DSP400L-0304-BA output voltages?
It provides two DC output channels: 4.2VDC and 3.2VDC. The connected equipment must be designed for these voltage rails.
What input voltage does the BA model accept?
The listed input range is 90-264VAC at 47-63Hz. The normal operating input range is 100-240VAC.
What is the rated output power?
The listed normal output power is 321W. Confirm the actual load and required output distribution before installation.
How is the BA model different from DSP400L-0304?
The BA model provides 4.2VDC and 3.2VDC at 321W, while DSP400L-0304 provides 3.8VDC and 2.8VDC at 307W. They are not direct substitutes unless the equipment requirements match.
Can the XingXiu DSP400L-0304-BA power supply replace a standard 5V unit?
Not as a direct universal replacement. Voltage, connector, pinout, power, and mechanical compatibility must all be verified.
What are the enclosure dimensions?
The enclosure measures 180 x 68 x 26 mm. Allow additional space for connectors, cable bend radius, mounting, and airflow.
